I mark that file as suspicious because of the location is in /var/log and the file is executable despite the name is ended with .log

is the IPSec VPN client installed by default in every iDevice, or cydia installed it? I want to know of the file also exist in any other jailbroken iDevice

On iPad2, jailbroken: racoon.log exists even though no IPSec account is configured (but PPTP). On iPod4, jailbroken: racoon.log does not exist even though an IPSec account is configured (but not PPTP).
